Tones in the audible frequency range to test your hearing or clean your speaker
This app generates a constant tone (sine, square, triangle, or sawtooth wave) in the audible frequency range (20 Hz to 22 kHz), which may be adjusted in 1 Hz or 10 Hz increments. In addition, special sounds can be played to remove water from your speakers and to help you relax, meditate, and sleep better. Each of these main sections of our app is on a separate page, and more information about them will be displayed when you tap the About button. What else can this tone generator be used for? - Tuning musical instruments and testing audio equipment - To find out what is the highest frequency you can hear - To interact with your dog and stop him from barking (note: longer exposure to the high-frequency range can damage the dog's hearing). - To find out the frequency of your pure-tone tinnitus and also to provide some relief from it. - To induce calm and relaxing thoughts during meditation and to meditate effectively and successfully. Features: -- Simple user interface, select, and play the sounds. -- Two buttons to adjust the volume of the sounds. -- Swipe left or right to adjust the frequency by 10 Hz. -- Swipe up or down to adjust the frequency by 1 Hz. -- Free application, no intrusive ads -- No permissions are required. -- This app keeps the phone's screen on.
